Though, imo the Hobbit hate DOES include MORE reasons to hate, for a lover of the Tolkien universe that is, like: "poor interpretation of the book, poor use of LotR appendix story, changing appendix scenes(for god knows why), creating a long/boring set of movies (here's to "no hope for the 3rd movie"), changing wonderfully written plots/scenes just to add bad character development, including Legolas and the girl Elf...the list goes on and on.
While I did enjoy LotR overall, many of what you said about The Hobbit applies to LotR. Many changs were made to the books that never sat well with me.
